  • It's really a matter of bullet selection and the 7mm and 30 cal have a larger selection. I'm on limited funds and cannot afford to rebarrel more than once right now so giving myself the highest probability of developing a good load is a priority. Actually I'm going to go back to developing a long range load for my 30-06. Where I'm at now the longest shot I'll need is 600 yards on elk.
    I was thinking 7mm-300 wm.

    that's great too, but gr for gr the new 277 bullets have higher bcs than the 7mm counterparts. The 300 win mag case cant push the 190s that fast. im 7,mm A 7STW would make a big jump or a 7rum.

    the 300 win mag capacity is about all you can burn in a .277 bore realistically. A 7 mm can handle more powder in larger cases- so feed the beast!
    I still might do a 270 AI. It's just on the back burner for now.

    if you dont have a magnum- the 270-300 win mag was a great cartridge we came up with- pushes 140s to 3450, 165s to 3300 150s to 3375. 28" barrel

    Well I have a 260 AI barrel because since then I burned up my 22-250 barrel shot out. I still have the 270 win 22" barrel but the chamber is chattered from the factory. After the 260AI is built I'll decide whether to go for a 7mm-300WM of a 300 WM
    That site was really awesome. Sheesh how many years of loads and knowledge went down the tubes there. I think at least a decade.
    This is the home of the 270-300 Win Mag, and the 270 AI, 25-06AI, 338-06. 300rum, 30-378, 6.5-284, 22-243 and a few others.
